Electron Energy Loss Spectra

The normal method of background subtraction in quantitative EELS analysis involves fitting an expression of the form I=AE-r to an energy window preceding the edge of interest; E is energy loss, A and r are fitting parameters. The calculated fit is then extrapolated under the edge, allowing the required signal to be extracted. In the case where the characteristic energy loss is small (E < 100eV), the background does not approximate to this simple form. One cause of this is multiple scattering. Even if the effects of multiple scattering are removed by deconvolution, it is not clear that the background from the recovered single scattering distribution follows this simple form, and, in any case, deconvolution can introduce artefacts.The above difficulties are particularly severe in the case of Al-Li alloys, where the Li K edge at ~52eV overlaps the Al L2,3 edge at ~72eV, and sharp plasmon peaks occur at intervals of ~15eV in the low loss region. An alternative background fitting technique, based on the work of Zanchi et al, has been tested on spectra taken from pure Al films, with a view to extending the analysis to Al-Li alloys.

Clinical Cases

We described two clinical cases of ortho-k lenses fitting in patients with “non-typical” corneal curvature/diameter ratio. The main goal was to acknowledge effective and safe use of this myopia correction method in patients with corneal diameter greater than 11 mm. Individual approach to each patient is the key to a successful and safe ortho-k lenses fitting.

Stereotypes often guide our perceptions of members of social groups. However, research has yet to document what stereotypes may exist for the fastest growing youth demographic in the U.S.—biracial individuals. Across seven studies (N = 1,104) we investigate what stereotypes are attributed to various biracial groups, whether biracial individuals are stereotyped as more similar to their lower status monoracial parent group (trait hypodescent), and whether contact moderates these stereotypes. Results provide evidence of some universal biracial stereotypes that are applied to all biracial groups: attractive and not fitting in or belonging. We also find that all biracial groups are attributed a number of unique stereotypes (i.e., which are not associated with their monoracial parent groups). However, across all studies, we find little evidence of trait hypodescent and no evidence that the tendency to engage in trait hypodescent varies as a function of contact.

While small in number, the place of the Indian in South Africa has historically loomed large because of their strong commercial and professional middle class, international influence through India, the commitment of many Indians to the anti-apartheid struggle and the prominent role that they have played in political and economic life post-apartheid. A History of the Present is the first book-length overview of Indian South Africans in the quarter century following the end of apartheid. Based on oral interviews and archival research it threads a narrative of the lives of Indian South Africans that ranges from the working class men and women to the heady heights of the newly minted billionaires; the changes wrought in the fields of religion and gender; opportunities offered on the sporting fields; the search for roots both locally and in India that also witnesses the rise of transnational organizations. Indians in South Africa appear to be always caught in an infernal contradiction; too traditional, too insular, never fitting in, while also too modern, too mobile. While focusing on Indian South Africans, this study makes critical interventions into several charged political discussions in post-apartheid South Africa, especially the debate over race and identity, while also engaging in discussions of wider intellectual interest, including diaspora, nation, and citizenship.

AbstractSituational or persistent body fluid deficit (i.e., de- or hypo-hydration) is considered a significant health risk factor. Bioimpedance analysis (BIA) has been suggested as an alternative to less reliable subjective and biochemical indicators of hydration status. The present study aimed to compare various BIA models in the prediction of direct measures of body compartments associated with hydration/osmolality. Fish (n = 20) was selected as a biological model for physicochemically measuring proximate body compartments associated with hydration such as water, dissolved proteins, and non-osseous minerals as the references or criterion points. Whole-body and segmental/local impedance measures were used to investigate a pool of BIA models, which were compared by Akaike Information Criterion in their ability to accurately predict the body components. Statistical models showed that ‘volumetric-based’ BIA measures obtained in parallel, such as distance2/Rp, could be the best approach in predicting percent of body moisture, proteins, and minerals in the whole-body schema. However, serially-obtained BIA measures, such as the ratio of the reactance to resistance and the resistance adjusted for distance between electrodes, were the best fitting in predicting the compartments in the segmental schema. Validity of these results should be confirmed on humans before implementation in practice.

Distributed Brillouin Sensor

A high-order polynomial fitting method is proposed to accelerate the computation of double-Gaussian fitting in the retrieval of the Brillouin frequency shifts (BFS) in optical fibers showing two local Brillouin peaks. The method is experimentally validated in a distributed Brillouin sensor under different signal-to noise ratios and realistic spectral scenarios. Results verify that a sixth-order polynomial fitting can provide a reliable initial estimation of the dual local BFS values, which can be subsequently used as initial parameters of a nonlinear double-Gaussian fitting. The method demonstrates a 4.9-fold reduction in the number of iterations required by double-Gaussian fitting and a 3.4-fold improvement in processing time.
